NORDEN, Calif. (AP)  The search for a ski instructor who went missing at a Northern California ski resort was suspended at dusk Saturday, and rescue crews plan to resume looking for him Sunday morning.

The Placer County Sheriff”s Office says the search-and-rescue team plan to focus on an avalanche slide area as they look for 23-year-old Carson May at Sugar Bowl Ski Resort near Norden.

Friends reported him missing Friday morning after he didn”t make it home and his belonging were discovered in his locker at the ski resort.

Searchers honed in on an out-of-bounds ski area after authorities got pings Friday off the last known location of May”s cellphone.
